Global surface of Venus. The mapping of Venus refers to the process and results of human description of the geological features of the planet Venus.It involves surface radar images of Venus, construction of geological maps, and the identification of stratigraphic units, volumes of rock with a similar age.
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.

A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1] [2] It is created by a celestial body with an active interior dynamo.
Venus only has an induced magnetosphere formed by the Sun's magnetic field carried by the solar wind. [46] This process can be understood as the field lines wrapping around an obstacle—Venus in this case. The induced magnetosphere of Venus has a bow shock, magnetosheath, magnetopause and magnetotail with the current sheet. [46] [47]

The Knobstone Escarpment is a rugged geologic region in Southern Indiana. Physically, the Knobstone Escarpment is the most rugged terrain in Indiana. The highest hill in the area is Weed Patch Hill, with an elevation of 1,060 feet above sea level. The escarpment's most prominent feature is its steep hills, often called "knobs", and ravines.
Globe: map showing locations of observatories and contour lines giving horizontal magnetic intensity in μ T. The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time scales mostly arise from currents in the ionosphere ( ionospheric dynamo region ) and magnetosphere, and some changes can be traced to ...
